5 signs that your trademark is being used without permission

Illegal trademark use rarely starts with an obvious counterfeit. More often, the right holder notices the problem after the fact: sales drop, negative reviews appear, and customers complain about the quality of products that the right holder never actually produced.

Such situations occur particularly often on marketplaces, where product listings are created quickly, sellers change regularly, and the volume of goods is measured in millions of items. Meanwhile, many right holders and their official sellers fail to notice the infringement for a long time, simply because they do not know which red flags to look for.

Let’s examine five signs that may indicate your trademark is already being used without authorization.

1. Suspiciously cheap products under your brand have appeared on the marketplace

One of the most common signals is when goods under your brand (trademark) are sold significantly below the market price. For example, a brand officially sells products within a certain price range, but similar items suddenly appear on Wildberries or Ozon at a substantial discount. Of course, a low price in itself does not always mean a violation - sometimes it could be a clearance sale, parallel import, or an unauthorized reseller.

But if other warning signs appear at the same time, such as differences in packaging or poor reviews, you need to take a closer look. This is especially true in situations where the seller uses your trademark directly but is not listed among your official partners.

2. Customers complain about the quality of "your" product

Sometimes customers themselves become the first "detectors" of an infringement. A typical situation: a company receives complaints about poor product quality, defects, or discrepancies in specifications. Upon investigation, it turns out that the products were purchased from an unknown seller, and the brand has no connection to that particular batch. This is a dangerous signal because reputational damage occurs before the right holder can identify the source of the problem.

For the consumer, the differences between an official product and a counterfeit one are usually not obvious. If a familiar brand is on the packaging, any negativity is automatically transferred to the right holder.

Therefore, regular analysis of customer reviews and feedback often helps to detect the illegal use of a trademark before it becomes a large-scale problem.

3. Products with similar names or an "almost your" brand appear in search results

Infringers rarely act directly. Instead of exactly copying a trademark, they may use similar spellings: replacing individual letters, transliteration, visually similar designations, or shortened versions of the brand name.

At first glance, the difference may seem insignificant. But it is precisely these schemes that are often used to pass marketplace moderation and simultaneously create an association with the original brand in the buyer's mind. This is especially true for impulse-buy goods, where the user makes a decision quickly and does not always notice the difference in spelling.

If you notice an "almost yours" brand in the search results, it is a reason to check whether your trademark rights are being infringed.

4. Other sellers are using your photos, logo, or product description

Even if a seller does not explicitly mention your brand in the product title, it does not mean there is no infringement. Elements of brand identity are often used: logos, original photos, product listing designs, product descriptions, and brand graphics. In this way, sellers create the impression that the product is associated with the rightsholder, even though this is not actually the case.

Such use may violate not only trademark rights but also copyrights, and can create a risk of unfair competition. If a product listing visually resembles an official brand item but is posted by an unknown seller, the situation warrants a separate investigation.

5. You regularly find new cards after deleting old ones

One of the most telling signs is the persistent recurrence of violations. For example, a right holder files a complaint and the product listing is removed, but a few days later, a similar one appears with a different name, a modified SKU, or under a different seller. This situation indicates not an accidental infringement, but the systemic unauthorized use of a trademark. In such cases, one-off responses are no longer effective. Businesses need continuous monitoring; otherwise, the fight against infringers turns into endless and ineffective manual labor.

What to do if you find signs of a violation

If suspicions are confirmed, it is important not to limit yourself to just a screenshot of the product listing.

Typically, it is necessary to:

• Record evidence;

• Save links and seller details;

• Verify trademark usage;

• Prepare a complaint to the marketplace;

• Monitor for re-listings.

This is why rightsholders and official sellers are gradually moving toward automated solutions, such as ZIPDetect, which helps not only find potential violations but also streamline the complaint process.

To summarize: the earlier a rightsholder notices these signs, the lower the risk of losing sales and facing reputational damage. The key is to view trademark protection as a continuous process rather than a reaction to a problem that has already occurred.
